Cylindrical Lens 3D Display Layout for Vergence-Accommodation Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The vergence-accommodation conflict in near-to-eye 3D display technologies causes visual fatigue and dizziness due to misalignment of monocular focusing and binocular convergence, which existing technologies have not adequately addressed.
Innovation Solution
A display apparatus with a specific arrangement of pixel columns and sub-pixels, including a display panel with misaligned pixel and sub-pixel rows, a light-transmitting pad layer, and a cylindrical lens structure, which aligns monocular focusing and binocular convergence by ensuring that each eye receives multiple view points simultaneously through cylindrical lenses, thereby reducing visual fatigue and dizziness, and a cylindrical lens structure, and a display method that uses eye tracking to control sub-pixel display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional 3D display technologies are used, then binocular convergence is achieved, but monocular focusing and binocular convergence are not located on the same plane, causing visual fatigue and dizziness
Solution Approach 1:
The display panel is divided into multiple pixel columns and pixel islands, with each pixel column containing multiple pixel islands arranged in the first direction. Each pixel island includes multiple sub-pixels of the same color. This segmentation allows different regions to display different view points, enabling light field display that resolves the vergence-accommodation conflict.
Solution Approach 2:
The patent introduces a new dimension by arranging sub-pixels not only in rows but also in multiple pixel islands along the first direction within each pixel column. This multi-dimensional arrangement, combined with cylindrical lenses, creates multiple view points in the vertical direction, allowing monocular focusing and binocular convergence to be located on the same plane.
2Adaptability or versatility
If pixel columns and sub-pixels are arranged in specific patterns, then multiple view points are achieved, but manufacturing precision requirements increase
Solution Approach 1:
Different regions of the display panel have different functions: pixel columns are arranged in the second direction to provide horizontal viewing coverage, while pixel islands within each column are arranged in the first direction to provide vertical viewing coverage. Each pixel island's sub-pixels are specifically configured to work with cylindrical lenses to create localized view points, allowing multi-view capability without requiring uniform high-precision arrangement across the entire panel.
3Reliability
If cylindrical lenses are used to direct light to each eye, then vergence-accommodation conflict is reduced, but device complexity increases
Solution Approach 1:
The cylindrical lenses serve multiple functions: they direct light from specific pixel islands to the corresponding eye, create multiple view points in the vertical direction, and enable the display to resolve the vergence-accommodation conflict. By making the cylindrical lenses multi-functional, the patent reduces the need for additional separate components, thereby limiting the increase in device complexity.
